STEEL STOVE.

T 0 all whom it may concern:

Be it known that I, ADELBERT E. BRON- SON, Six, a citizen of the United States, residing at Cleveland, in the county of Guyahoga and State of Ohio, have invented a certain new and useful Improvement in Steel Stoves, of which the following is a full, clear, and exact description.

The object of this invention is to produce a sheet metal kitchen stove which will be cheap and durable.

The invention consists in the combinations of parts shown in the drawings and hereinafter described and pointed out in the claims.

In the drawing, Figure l is a planview of a stove embodying the invention. Fig. 2 is a sectional end view in the plane of line 22 on Fig. 1. Fig. 3 is a sectional plan view in the plane of line 3-3 on Fig. 4. Fig. 4 is a front view partly in section in the plane of line 44: on Fig. 3.

Referring to the parts by letters, A represents the top member, B the bottom member, and G the body part of a stove embodying the invention, all made of sheet steel cut and bent into the forms shown. The bottom member B has a raised center 6, and a down-turned marginal flange 6'. There is preferably in said member B, a groove 6 of which the marginal edge of the raised portion Z) forms one wall.

The stove body, which includes the front, back and two ends, is made of two pieces C, C. The piece C is bent so as to form the two ends c, 0 and back 0, which is at right angles to said ends. The front edges of the two ends are bent toward each other to form the two flanges c 0*, which are parallel with the back. At the corners of this member the metal is bent outward to form the hollow columns 0 These columns permit the expansion and contraction of the body by the various heats it is subjected to without causing any substantial variation in the size or shape of the body as an entirety. They also serve as housings to protect the vertical bolts D, whose function and disposition will be presently described; and they likewise. improve the appearance of the stove.

The front member C has through it open ing's to the oven, the ash pit and the fire pot, the marginal edges of these openings being preferably bent inward to form narrow Specification of Letters Patent.

flanges c, c. The vertical edges of the front member are secured by stove bolts 0 to the flanges 0 0*. The top member A is formed of a single plate from which the middle portion has been cut, and the remainder pressed into substantially the form shown. The outer edges of this plate are turned down to form a flange (4. Just inside of this flange is a horizontal part a which forms a part of the stove top. Along the inner margin of this horizontal part the metal is bent downward and then inward horizontally to form what amounts to a rabbeted groove (4 The stove top G is fitted to and is supported in this rabbeted groove. Just within this groove is a downwardly and inwardly curved portion a around whose inner edge is a down turned flange at This flange fits within the open top of the body,-the adjacent part of the curved portion a being substantially horizontal so that it may rest upon the top of said body. In assembling these parts, the

bottom edges of the body are set into the groove 6 The flange a of the top member A is fitted into the top of the body. Four vertical bolts D pass through the bottom member B, then up through the several tubular columns 0 and through the part a just above said columns. When the nuts on these bolts are tightened up the parts specified are held securely in the described relation to one another.

The top Gr, before mentioned,may be made of cast iron, and may be provided with the required lid-covered opening g, and preferably with a flanged opening 9 over which a stove pipe may be secured.

The oven is formed of several sheet steel plates as follows. The left end H is formed of two plates h, h. The plate 72. has a flange h on its lower edge which rests upon the bottom member B, to which it is secured by stove bolts. This plate is bent as shown to form the ledge h Along its upper edge this plate is bent to form an upwardly opening cup joint k which receives the lower edge of the plate It. These two plates not only form a part of the oven, but they serve also as the righthand walls of the ash pit and the combustion chamber. The upper edge of the part h, which lies at one side of the ash pit, is about at the level of the grate, and this sheet will not, therefore, be exposed to injurious heat, but the sheet h, at the side of the combustion chamber, will be subjected to the destructive influence of the heat, even though lined, to a greater degree than will the part 71, and is more exposed to deterioration than is said part 7L. It is for this reason that this particular vertical wall is made of two pieces instead of one, because, if the upper part it. is burned out, it may be easily replaced by another similar part.

The top and right end plates of the oven are formed of one piece J The lower edge of the right end is a considerable distance above the bottom member B and is turned inward and upward to form a groove The back oven plate K has its lower edge in the same plane with the lower edge of the right end, and is also turned inward and upward to form a groove 7:. The rear plate K, near its vertical edges is bent to form a reaiuvardly projecting bead 7:. The grooves in front of these beads receive the rear edges of the two end plates of the oven; and the rearwardly projecting beads fit into vertical grooves 0 pressed into the rear plate 0 of the body. This rear plate is pressed rearwardly so as to form the vertical flue pocket F; and the rear oven plate K serves to cover the front of this pocket and to thereby complete the vertical flue. The upper edges of the plates h and K are bent over upon the horizontal part of the plate J, and the flange of the plate It secured thereto by stove bolts, and thereby downward movement of said oven plates independent of plate J is prevented. Four horizontal bolts N pass through the front and rear members of the body and tie them together. The top oven plate rests upon the two upper bolts which lie close in the upper corners of the oven, whereby it receives the greater portion of its support. It will be noted, by reference to Fig. at, that the upper corners of the oven opening in the front of the stove, are not cut out squarely, but are rounded as shown, at the upper left hand corner, so as to leave metal through which the upper bolts N pass. The bottom oven plate M has on its rear edge and right edge downwardly turned flanges m, m, which respectively enter the grooves 7.: and j, while the left end of said bottom plate rests on the ledge h The top oven plate and the two end oven plates bear against the inwardly turned flange 0 around the oven opening through the front member C of the body, and the front edge of the bottom plate M rests upon the horizontal flange 0 along the lower edge of said opening.

It will be noted that the described stove may be made wholly of sheet steel cut and pressed into the desired shape,only nine pieces being required for making a complete stove exclusive of the doors for the ash pit, fire pot and oven, and the top G. These nine pieces, together with a few stove bolts, make a stove which is quite as eflicient as any cast iron stove, is much cheaper and much lighter, much more durable, and much less liable to become accidentally injured.

Having described my invention I claim:

1. The combination of a bottom member having a groove in its top, a body member whose lower edge is seated in said groove and which has at its corners integral outwardly bent tubular columns, a top member having an open center provided with a down turned marginal flange which fits into the top of said body member and which has outside of said flange an outwardly and upwardly curved portion which rests upon the top of said body part, and vertical bolts passing through the outwardly and upwardly curved part of the top member down through said tubular columns and through the bottom member.
